PROCESS OF MAKING AND FILLING BAGS.

Specification of Letters Patent.

Patented Sept. 21, 1920.

Application filed March 27, 1919. Serial No. 285,895.

To all whom it may concern:

Be it known that I, ADELMER BATES, acitizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented a certain new and useful Improvement in Processes of Making and Filling Bags, of which the following is a specification.

My invention relates to a method or process of making and filling bags of material from a continuous roll of fabric. It is illustrated diagrammatically in the accompanying drawings where I have shown, however, diagrammatically, a mechanism which might be manipulated to carry out my method. It

will, however, be recognized that the method might be carried out by totally different machines or without any at all, except such devices as are necessary to support the bag of material from time to time.

Figure 1 is an elevation of the upper portion of the apparatus for carrying out my process and, Fig. 2 is an elevation of the lower part of said apparatus. Like parts are indicated by the same letters in each of the drawings.

Referring to the drawing, A is a hopper with its supply of material. B is a receptacle holding a measured or weighted charge. 0 is a filling funnel and D is a filling tube depending therefrom and suitably mounted or supported. E is an outer or larger tube which incloses the filling tube. F is a roll of fabric fed forward or up wardly by feedin rolls G, one on each side of the tube E. 4 f course, the feeding forward of the tube or fabric could be accom- G is a sewing and clamping apparatus shown merely in diagram but intended to draw the fabric around the tube E, form it into a tube and stretch the edges. G G are rolls properly positioned and adapted to draw the tube downwardly between the feed tube and the outer tube. From this point the tube passes downwardly and it may be puckered or gathered as at G The tube is now flattened out in any desired manner by hand or otherwise so as to assume the flat shape indicated at J and at this flattened portion it may be clamped as at J or at J or at both places. The idea is to stretch the tube so as to bring its sides into proper relation for the clamping at J 2 and for the subsequent sewing and severingf When the goods is clamped at J the measured charge J may be discharged above such clamp, or when the goods is clamped only at J the measured charge may be discharged as soon as the clamping is effected at that point upon the goods above such clamp.

K is a sewing and cloth severing device adapted to form two separated seams across the flattened tube, one seam just below the section above the point J and the other just above the filled bag section. The material is severed between the two seams thus forming the bottom of the bag next to be formed and the top of the filled bag section L below. This filled bag section for suchseaming and severing is preferably supported as for instance at M on a jigging table which is operated by the jigging device N so as to settle the material in the bag and fill out its bottom portion. This material is also ering at the top portion of the section to be filled by compressing the material within such upper portion and this may be done by the pressure device 0 O. In the pre ferred method of operating my invention after the lower portion of the bag section has been filled out or the charge settled or after the charge has been deposited in such lower portion it is pulled up and then the upper compressing device 0 O is operated so as to properly settle or compress or pack the charge within the bag section L. The precise order of these several steps will of course, be carried out to suit the convenience of theoperator or to adapt the method to the machine or machines which may be employed in carrying out the method.

I shall state the method in more general terms.

The use and operation of my invention are as follows:

A roll of bag material suitably mounted is preferably drawn forwardly .-.or upwardly between feeding rolls and its two longitudinal edges are stitched together to form a tube which is folded down within itself, the

tube or bag material being properly suping device, and there is preferably a long interval between such clamp and the support of the tube, so that there maybe any desired amount of slack or'puckering in the tube. This makes it possib e to operate the mechanism which makes the seam for the tube and the mechanism which makes the stitching across the tube to form the bag separately and not in synchron sm, In other words, the two operations are entirely independent of each other, however they maybe carried on, and the bag or tube materlal between them may be accumulated to any reasonable extent. A measured quantity of material is dropped into the tube and it falls into the lower bag section of the tube, resting against the clamp or thecloth of the tube at a point where its two sides are held together by the clamp. The tube is now stitched across below the clamp and the cloth cut. below such stitching so as to form a closed end for such bag section. The clamp now opens and the bag drops to the jigging table, the material beingthus settled or com pressed and the botto of the bag filled out. The bag is jigged in any desired manner and to any degree to effect the settling of the material. The filled bag section may then be lifted up by a pull on the bag tube and the cloth of the tube about the upper portion of the filling charge is pressed down so as to fill out the upper portion of the bag, compressing the naterial in it. The tube above such filled bag is then clamped and the next charge of material is dropped into the bag tube and held above the clamp while the two seams are run across the tube at ti ii the same time and the material between them is'cut and the processycontinued. Of course, these several steps neednot all of them be carried out in the precise order indicated, but with any ordinary form of mechanism, it would be found convenient to proceed substantially as proposed above. It is also obvious that each successive bag could be formed separately, but in the case of employment of mechanism," it is plain that as the top of one bag is completed the bottom of the next should be also completed so that the process becomes continuous.
